MARCH 31, 2009


A Letter to Shareholders

The past 12 months have been a period investors would like to forget, but instead will vividly remember, as the global financial crisis erupted into

the worst recession in decades. Daily headlines recounted the downfalls of storied financial firms, volatile swings in the world’s financial markets and

monumental government actions, including the recent passage of the nearly $800 billion American Recovery and Reinvestment Act of 2009.

The economic data generally deteriorated throughout the reporting period. US gross domestic product (“GDP”) contracted at an annual rate of 6.3% in

the fourth quarter of 2008, and economic activity appears on pace to be negative in the first quarter of 2009 as well. The Federal Reserve Board (the

“Fed”) took forceful action to revive the global economy and ailing financial system. In addition to slashing the federal funds target rate from 3.0% to

a record low range of 0% to 0.25%, the central bank provided enormous cash infusions and radically expanded its balance sheet through a range of

lending and acquisition programs.

Against this backdrop, US equities contended with high levels of volatility and posted steep losses, notwithstanding a powerful rally in the final month

of the reporting period. International markets also experienced sharp downturns, with some regions declining as much or more than the United States.

Risk aversion remained the dominant theme in fixed income markets, as investors sought out the haven of Treasury issues at the expense of virtually

all other asset classes. High yield issues, in particular, faced unprecedented challenges and posted severe underperformance; that said, the sector

pared its losses in the first quarter of 2009, as both liquidity and investor sentiment toward lower-quality debt improved. At the same time, the start of

the new year brought somewhat of a return to normalcy for the tax-exempt market, which registered one of its worst years on record in 2008.

In all, investors continued to gravitate toward relative safety, as evidenced in the six- and 12-month returns of the major benchmark indexes:

Total Returns as of March 31, 2009  6-month  12-month 
US equities (S&P 500 Index)  (30.54)%  (38.09)% 
Small cap US equities (Russell 2000 Index)  (37.17)  (37.50) 
International equities (MSCI Europe, Australasia, Far East Index)  (31.11)  (46.50) 
US Treasury securities (Merrill Lynch 10-Year US Treasury Index)  11.88  10.46 
Taxable fixed income (Barclays Capital US Aggregate Bond Index)  4.70  3.13 
Tax-exempt fixed income (Barclays Capital Municipal Bond Index)  5.00  2.27 
High yield bonds (Barclays Capital US Corporate High Yield 2% Issuer Capped Index)  (12.65)  (18.56) 

Past performance is no guarantee of future results. Index performance shown for illustrative purposes only. You cannot invest directly in an index.

multiplied by the average account value over the period, multiplied by 182/365 (to reflect the one-half year period shown). Because the Fund is a feeder fund, the expense
table example reflects the expenses of both the feeder fund and the master fund in which it invests.

8 WCMA TAX-EXEMPT FUND

MARCH 31, 2009


Notes to Financial Statements WCMA Tax-Exempt Fund

1. Organization and Significant Accounting Policies:

WCMA Tax-Exempt Fund the (“Fund”) is registered under the Investment
Company Act of 1940, as amended (the “1940 Act”), as a no load,
diversified, open-end management investment company. The Fund is
organized as a Massachusetts business trust. The Fund seeks to achieve
its investment objective by investing all of its assets in Master Tax-Exempt
LLC (the “Master LLC”), which has the same investment objective and
strategies as the Fund. The Master LLC is organized as a Delaware lim-
ited liability company. The value of the Fund’s investment in the Master
LLC reflects the Fund’s proportionate interest in the net assets of the
Master LLC. The performance of the Fund is directly affected by the per-
formance of the Master LLC. The financial statements of the Master LLC,
including the Schedule of Investments, are included elsewhere in this
report and should be read in conjunction with the Fund’s financial state-
ments. The Board of Trustees of the Fund and the Board of Directors of
the Master LLC are referred to throughout this report as the “Board of
Directors” or the “Board.” The Fund’s financial statements are prepared
in conformity with accounting principles generally accepted in the United
States of America, which may require the use of management accruals
and estimates. Actual results may differ from these estimates. The per-
centage of the Master LLC owned by the Fund at March 31, 2009 was
9.5%. The Fund is divided into four classes, designated Class 1, Class 2,
Class 3 and Class 4. Each Class 1, Class 2, Class 3 and Class 4 Share
represents an interest in the same assets of the Fund and has identical
voting, dividend, liquidation and other rights and the same terms and
conditions, except that each class bears certain expenses related to the
service and distribution of such shares and the additional incremental
transfer agency costs resulting from the conversion of shares and has
exclusive voting rights with respect to matters relating to such share-
holder services and distribution expenditures.

The following is a summary of significant accounting policies followed by
the Fund:

Valuation of Investments: The Fund records its investment in the Master
LLC at fair value. Valuation of securities held by the Master LLC is dis-
cussed in Note 1 of the Master LLC’s Notes to Financial Statements,
which are included elsewhere in this report. The Fund seeks to maintain
the net asset value per share at $1.00, although there is no assurance
that it will be able to do so on a continuing basis.

Effective April 1, 2008, the Fund adopted Financial Accounting Standards
Board Statement of Financial Accounting Standards No. 157, “Fair Value
Measurements” (“FAS 157”). FAS 157 clarifies the definition of fair
value, establishes a framework for measuring fair values and requires
additional disclosures about the use of fair value measurements. Various
inputs are used in determining the fair value of investments, which are
as follows:

Level 1 — price quotations in active markets/exchanges for identical
securities

Level 2 — other observable inputs (including, but not limited to:
quoted prices for similar assets or liabilities in markets that are
active, quoted prices for identical or similar assets in markets that
are not active, inputs other than quoted prices that are observable
for the assets or liabilities (such as interest rates, yield curves,
volatilities, prepayment speeds, loss severities, credit risks and

Level 3 — unobservable inputs based on the best information avail-
able in the circumstance, to the extent observable inputs are not
available (including the Fund’s own assumptions used in determining
the fair value of investments)

The inputs or methodology used for valuing securities are not necessarily
an indication of the risk associated with investing in those securities.

The following table summarizes the inputs used as of March 31, 2009 in
determining the fair valuation of the Fund’s investments:

Valuation  Investments in

Level 3   
Total  $1,080,838,795 

Investment Transactions and Net Investment Income: Investment trans-
actions in the Master LLC are accounted for on a trade date basis. The
Fund records daily its proportionate share of the Master LLC’s income,
expenses and realized gains and losses. In addition, the Fund accrues
its own income and expenses. Income and realized gains and losses are
allocated daily to each class based on its relative net assets.

Dividends and Distributions to Shareholders: Dividends from net invest-
ment income are declared and reinvested daily and paid monthly. Distri-
butions of realized gains, if any, are recorded on the ex-dividend dates.

Income Taxes: It is the Fund’s policy to comply with the requirements of
the Internal Revenue Code applicable to regulated investment companies
and to distribute substantially all of its taxable income to its shareholders.
Therefore, no federal income tax provision is required.

The Fund files US federal and various state and local tax returns. No
income tax returns are currently under examination. The statute of
limitations on the Fund’s US federal tax returns remains open for the
four years ended March 31, 2009. The statutes of limitations on the
Fund’s state and local tax returns may remain open for an additional
year depending upon the jurisdiction.

Recent Accounting Pronouncement: In March 2008, Statement of
Financial Accounting Standards No. 161, “Disclosures about Derivative
Instruments and Hedging Activities — an amendment of FASB Statement

WCMA TAX-EXEMPT FUND

MARCH 31, 2009

9


Notes to Financial Statements (continued) WCMA Tax-Exempt Fund

No. 133” (“FAS 161”), was issued. FAS 161 is intended to improve
financial reporting for derivative instruments by requiring enhanced
disclosure that enables investors to understand how and why an entity
uses derivatives, how derivatives are accounted for, and how derivative
instruments affect an entity’s results of operations and financial position.
FAS 161 is effective for financial statements issued for fiscal years and
interim periods beginning after November 15, 2008. The impact on the
Fund’s financial statement disclosures, if any, is currently being assessed.

Other: Expenses directly related to the Fund or its classes are charged to
that Fund or class. Other operating expenses shared by several funds are
pro-rated among those funds on the basis of relative net assets or other
appropriate methods. Other expenses of the Fund are allocated daily to
each class based on its relative net assets.

2. Transactions with Affiliates:

The Fund has entered into an Administration Agreement with BlackRock
Advisors, LLC (the “Administrator”), an indirect, wholly owned subsidiary
of BlackRock, Inc. to provide administrative services (other than invest-
ment advice and related portfolio activities). For such services, the Fund
pays the Administrator a monthly fee at an annual rate of 0.25% of the
average daily value of the Fund’s net assets. The PNC Financial Services
Group, Inc. (“PNC”) and Bank of America Corporation (“BAC”) are the
largest stockholders of BlackRock, Inc. (“BlackRock”). BAC became a
stockholder of BlackRock following its acquisition of Merrill Lynch & Co.,
Inc. (“Merrill Lynch”) on January 1, 2009. Prior to that date, both PNC
and Merrill Lynch were considered affiliates of the Fund under the 1940
Act. Subsequent to the acquisition, PNC remains an affiliate, but due to
the restructuring of Merrill Lynch’s ownership interest of BlackRock, BAC
is not deemed to be an affiliate under the 1940 Act.

Effective October 1, 2008, the Fund entered into a Distribution Agreement
and Distribution Plans with BlackRock Investments, LLC (“BIL”), which
replaced Merrill Lynch, Pierce, Fenner and Smith Incorporated (“MLPF&S)
(collectively, the “Distributor”) as the sole distributor of the Fund. MLPF&S
is a wholly owned subsidiary of Merrill Lynch. BIL is an affiliate of
BlackRock. The service and distribution fees did not change as a
result of the transaction.

Pursuant to the Distribution Plans adopted by the Fund in accordance
with Rule 12b-1 under the 1940 Act, the Fund pays the Distributor serv-
ice and distribution fees. The fees are accrued daily and paid monthly at
annual rates based upon the average daily net assets of the shares of
the Fund as follows:

  Service  Distribution 
  Fee  Fee 
Class 1  0.25%  0.750% 
Class 2  0.25%  0.425% 
Class 3  0.25%  0.125% 
Class 4  0.25%  0.125% 

The ongoing service and/or distribution fee compensates the Distributor
for providing shareholder servicing and/or distribution-related services to
shareholders. The Fund has entered into a contractual arrangement with
the Administrator and BIL to waive and/or reimburse a portion of the
Fund’s fees and expenses to ensure that the net expenses for the Fund’s
Class 2 Shares is 0.35% higher than that of CMA Tax-Exempt Fund, and
Class 3 and Class 4 Shares is equal to that of CMA Tax- Exempt Fund
as applicable. The fee/expense waiver or reimbursement includes serv-
ice and distribution fees. This arrangement has a one-year term and is
renewable. These amounts are included in service and distribution fees
waived on the Statement of Operations.

The Distributor has voluntarily agreed to waive its distribution fees to
enable each class of the Fund to maintain a minimum daily net invest-
ment income dividend. These amounts are included in service and distri-
bution fees waived on the Statement of Operations. The Distributor may
discontinue the waiver at any time.

Financial Data Services, Inc. (“FDS”), a wholly owned subsidiary of Merrill
Lynch, serves as transfer agent. The Fund may earn interest on positive
cash balances in demand deposit accounts that are maintained by FDS
on behalf of the Fund. This amount is shown as interest — affiliated on
the Statement of Operations.

Certain officers and/or directors of the Fund are officers and/or directors
of BlackRock, Inc. or its affiliates. The Fund reimburses the Administrator
for compensation paid to the Fund’s Chief Compliance Officer.

3. Capital Share Transactions:

The number of shares sold, reinvested and redeemed correspond to the
net proceeds from sale of shares, reinvestments of dividends and cost of
shares redeemed, respectively, since shares are sold and redeemed at
$1.00 per share.

Transactions in shares for each class were as follows:

  Year Ended

4. Federal Insurance:     

The Fund participates in the US Treasury Department’s Temporary
Guarantee Program for Money Market Funds (the “Program”). As a result
of the Fund’s participation in the Program, in the event the Fund’s net
asset value falls below $0.995 per share, shareholders in the Fund will
have federal insurance of $1.00 per share up to the lesser of sharehold-
ers’ balances in the Fund as of the close of business on September 19,

2008, or the remaining balances of such shareholder accounts as of the
date the guarantee is triggered. Any increase in the number of shares in
a shareholder’s balance after the close of business on September 19,
2008 and any future investments after a shareholder has closed their
account will not be guaranteed. As a participant of the Program, which
expires September 18, 2009, the Fund paid a participation fee of
0.01% for the period September 19, 2008 through December 18, 2008
and 0.03% for the period December 19, 2008 through September 18,
2009 of the Fund’s shares outstanding value as of September 19, 2008.
The participation fee for the period September 19, 2008 to March 31,
2009 is included in federal insurance on the Statement of Operations.

5. Income Tax Information:

Reclassification: Accounting principles generally accepted in the United
States of America require that certain components of net assets be
adjusted to reflect permanent differences between financial and tax
reporting. The following permanent differences as of March 31, 2009
attributable to the use of equalization were reclassed to the following
accounts:

Paid-in capital in excess of par  $ 118,570 
Accumulated net realized gain allocated from the Master LLC  $(118,570) 

The tax character of distributions paid during the fiscal years ended
March 31, 2009 and March 31, 2008 were as follows:

  3/31/2009  3/31/2008 
Distributions paid from:     
   Tax-exempt income  $ 13,188,709  $26,259,863 
   Net long-term capital gains  118,570   
Total distributions  $ 13,307,279  $26,259,863 

As of March 31, 2009, there were no significant differences between the
book and tax components of net assets.

Report of Independent Registered Public Accounting Firm WCMA Tax-Exempt Fund

To the Shareholders and Board of Directors of
WCMA Tax-Exempt Fund:

We have audited the accompanying statement of assets and liabilities
of WCMA Tax-Exempt Fund (the “Fund”) as of March 31, 2009, and the
related statement of operations for the year then ended, the statements
of changes in net assets for each of the two years in the period then
ended, and the financial highlights for each of the five years in the
period then ended. These financial statements and financial highlights
are the responsibility of the Fund’s management. Our responsibility is to
express an opinion on these financial statements and financial high-
lights based on our audits.

We conducted our audits in accordance with the standards of the Public
Company Accounting Oversight Board (United States). Those standards
require that we plan and perform the audit to obtain reasonable assur-
ance about whether the financial statements and financial highlights are
free of material misstatement. The Fund is not required to have, nor were
we engaged to perform, an audit of its internal control over financial
reporting. Our audits included consideration of internal control over
financial reporting as a basis for designing audit procedures that are
appropriate in the circumstances, but not for the purpose of expressing

an opinion on the effectiveness of the Fund’s internal control over finan-
cial reporting. Accordingly, we express no such opinion. An audit also
includes examining, on a test basis, evidence supporting the amounts
and disclosures in the financial statements, assessing the accounting
principles used and significant estimates made by management, as well
as evaluating the overall financial statement presentation. We believe
that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of
WCMA Tax-Exempt Fund as of March 31, 2009, the results of its opera-
tions for the year then ended, the changes in its net assets for each of
the two years in the period then ended, and the financial highlights for
each of the five years in the period then ended, in conformity with
accounting principles generally accepted in the United States of
America.

Effective April 1, 2008, the Master LLC adopted Financial Accounting Standards
Board Statement of Financial Accounting Standards No. 157, “Fair Value
Measurements” (“FAS 157”). FAS 157 clarifies the definition of fair value, estab-
lishes a framework for measuring fair values and requires additional disclosures
about the use of fair value measurements. Various inputs are used in determining
the fair value of investments, which are as follows:
Level 1 — price quotations in active markets/exchanges for identical securities
Level 2 — other observable inputs (including, but not limited to: quoted prices
for similar assets or liabilities in markets that are active, quoted prices for
identical or similar assets in markets that are not active, inputs other than
quoted prices that are observable for the assets or liabilities (such as interest
rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks
and default rates) or other market-corroborated inputs)
Level 3 — unobservable inputs based on the best information available
in the circumstance, to the extent observable inputs are not available
(including the Master LLC’s own assumptions used in determining the fair
value of investments)
The inputs or methodology used for valuing securities are not necessarily an indica-
tion of the risk associated with investing in those securities. For information about
the Master LLC’s policy regarding valuation of investments and other significant
accounting policies, please refer to Note 1 of the Notes to Financial Statements.
The following table summarizes the inputs used as of March 31, 2009 in deter-
mining the fair valuation of the Master LLC’s investments:

Valuation  Investments in 
Inputs  Securities

Level 1   
Level 2  $11,317,358,460

Notes to Financial Statements Master Tax-Exempt LLC

1. Organization and Significant Accounting Policies:

Master Tax-Exempt LLC (the “Master LLC”) is registered under the
Investment Company Act of 1940, as amended (the “1940 Act”), and
is organized as a Delaware limited liability company. The Limited Liability
Company Agreement permits the Directors to issue nontransferable inter-
ests in the Master LLC, subject to certain limitations. The Board of
Trustees of the Fund and the Board of Directors of the Master LLC
are referred to throughout this report as the “Board of Directors” or the
“Board.” The Master LLC’s financial statements are prepared in con-
formity with accounting principles generally accepted in the United
States of America, which may require the use of management accruals
and estimates. Actual results may differ from these estimates.

The following is a summary of significant accounting policies followed by
the Master LLC:

Valuation of Investments: The Master LLC securities are valued under
the amortized cost method which approximates current market value in
accordance with Rule 2a-7 of the 1940 Act. Under this method, securi-
ties are valued at cost when purchased and thereafter, a constant pro-
portionate amortization of any discount or premium is recorded until
the maturity of the security.

Investment Transactions and Investment Income: Investment trans-
actions are recorded on the dates the transactions are entered into
(the trade dates). Realized gains and losses on security transactions are
determined on the identified cost basis. Interest income is recognized on
the accrual basis. The Master LLC amortizes all premiums and discounts
on debt securities.

Income Taxes: The Master LLC is classified as a partnership for federal
income tax purposes. As such, each investor in the Master LLC is
treated as owner of its proportionate share of the net assets, income,
expenses and realized and unrealized gains and losses of the Master
LLC. Therefore, no federal income tax provision is required. It is intended
that the Master LLC’s assets will be managed so an investor in the
Master LLC can satisfy the requirements of Subchapter M of the Internal
Revenue Code.

The Master LLC files US federal and various state and local tax returns.
No income tax returns are currently under examination. The statute of
limitations on the Master LLC’s US federal tax returns remains open for
each of the four years ended March 31, 2009. The statutes of limitations
on the Master LLC’s state and local tax returns may remain open for an
additional year depending upon the jurisdiction.

Recent Accounting Pronouncement: In March 2008, Statement
of Financial Accounting Standards No. 161, “Disclosures about
Derivative Instruments and Hedging Activities — an amendment of FASB
Statement No. 133” (“FAS 161”), was issued. FAS 161 is intended
to improve financial reporting for derivative instruments by requiring

enhanced disclosure that enables investors to understand how and why
an entity uses derivatives, how derivatives are accounted for, and how
derivative instruments affect an entity’s results of operations and financial
position. FAS 161 is effective for financial statements issued for fiscal
years and interim periods beginning after November 15, 2008. The
impact on the Master LLC’s financial statement disclosures, if any, is cur-
rently being assessed.

Other: Expenses directly related to the Master LLC are charged to that
Master LLC. Other operating expenses shared by several funds are pro-
rated among those funds on the basis of relative net assets or other
appropriate methods.

2. Investment Advisory Agreement and Other Transactions
with Affiliates:

The Master LLC has entered into an Investment Advisory Agreement with
BlackRock Advisors, LLC (the “Advisor”), an indirect, wholly owned sub-
sidiary of BlackRock, Inc., to provide investment advisory and adminis-
tration services. The PNC Financial Services Group, Inc. (“PNC”) and
Bank of America Corporation (“BAC”) are the largest stockholders of
BlackRock, Inc. (“BlackRock”). BAC became a stockholder of BlackRock
following its acquisition of Merrill Lynch & Co., Inc. (“Merrill Lynch”) on
January 1, 2009. Prior to that date, both PNC and Merrill Lynch were
considered affiliates of the Master LLC under the 1940 Act. Subsequent
to the acquisition, PNC remains an affiliate, but due to the restructuring
of Merrill Lynch’s ownership interest of BlackRock, BAC is not deemed to
be an affiliate under the 1940 Act.

The Advisor is responsible for the management of the Master LLC’s
investments and provides the necessary personnel, facilities, equipment
and certain other services necessary to the operations of the Master
LLC. For such services, the Master LLC pays the Advisor a monthly fee
based upon the average daily value of the Master LLC’s net assets at
the following annual rates: 0.25% of the Master LLC’s average daily net
assets not exceeding $500 million; 0.175% of the average daily net
assets in excess of $500 million, but not exceeding $1 billion; and
0.125% of the average daily net assets in excess of $1 billion.

The Advisor has entered into a separate sub-advisory agreement with
BlackRock Investment Management, LLC (“BIM”), an affiliate of the
Advisor, under which the Advisor pays BIM, for services it provides, a
monthly fee that is a percentage of the investment advisory fee paid by
Master LLC to the Advisor.

For the year ended March 31, 2009, the Master LLC reimbursed the
Advisor $205,886 for certain accounting services, which is included in
accounting services in the Statement of Operations.

Pursuant to the terms of the custody agreement, custodian fees may
be reduced by amounts calculated on uninvested cash balances, which
are shown on the Statement of Operations as fees paid indirectly.

Notes to Financial Statements (concluded)

Master Tax-Exempt LLC

Certain officers and/or directors of the Master LLC are officers
and/or directors of BlackRock, Inc. or its affiliates. The Master LLC
reimburses the Advisor for compensation paid to the Master LLC’s
Chief Compliance Officer.

3. Market and Credit Risk:

In the normal course of business, the Master LLC invests in securities
and enters into transactions where risks exist due to fluctuations in the
market (market risk) or failure of the issuer of a security to meet all its
obligations (credit risk). The value of securities held by the Master LLC
may decline in response to certain events, including those directly
involving the issuers whose securities are owned by the Master LLC;
conditions affecting the general economy; overall market changes;
local, regional or global political, social or economic instability; and
currency and interest rate and price fluctuations. Similar to credit risk,
the Master LLC may be exposed to counterparty risk, or the risk that
an entity with which the Master LLC has unsettled or open transactions
may default. Financial assets, which potentially expose the Master LLC
to credit and counterparty risks, consist principally of investments and
cash due from counterparties. The extent of the Master LLC’s exposure
to credit and counterparty risks with respect to these financial assets
is approximated by their value recorded in the Master LLC’s Statements
of Assets and Liabilities.

We have audited the accompanying statement of assets and liabilities,
including the schedule of investments, of Master Tax-Exempt LLC (the
“Master LLC”) as of March 31, 2009, and the related statement of oper-
ations for the year then ended, the statements of changes in net assets
for each of the two years in the period then ended, and the financial
highlights for each of the five years in the period then ended. These
financial statements and financial highlights are the responsibility of the
Master LLC’s management. Our responsibility is to express an opinion on
these financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public
Company Accounting Oversight Board (United States). Those standards
require that we plan and perform the audit to obtain reasonable assur-
ance about whether the financial statements and financial highlights
are free of material misstatement. The Master LLC is not required to
have, nor were we engaged to perform, an audit of its internal control
over financial reporting. Our audits included consideration of internal
control over financial reporting as a basis for designing audit procedures
that are appropriate in the circumstances, but not for the purpose of
expressing an opinion on the effectiveness of the Master LLC’s internal
control over financial reporting. Accordingly, we express no such opinion.

An audit also includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by manage-
ment, as well as evaluating the overall financial statement presentation.
Our procedures included confirmation of securities owned as of March
31, 2009, by correspondence with the custodian and brokers; where
replies were not received from brokers, we performed other auditing
procedures. We believe that our audits provide a reasonable basis for
our opinion.

In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position
of Master Tax-Exempt LLC as of March 31, 2009, the results of its
operations for the year then ended, the changes in its net assets
for each of the two years in the period then ended, and the financial
highlights for each of the five years in the period then ended, in con-
formity with accounting principles generally accepted in the United
States of America.

Item 2 – Code of Ethics – The registrant (or the “Fund”) has adopted a code of ethics, as of the end
of the period covered by this report, applicable to the registrant’s principal executive officer,
principal financial officer and principal accounting officer, or persons performing similar
functions. During the period covered by this report, there have been no amendments to or
waivers granted under the code of ethics. A copy of the code of ethics is available without
charge at www.blackrock.com.

applicable (the “board of directors”) has determined that (i) the registrant has the following
audit committee financial expert serving on its audit committee and (ii) each audit
committee financial expert is independent:
Kenneth L. Urish

Under applicable securities laws, a person determined to be an audit committee financial
expert will not be deemed an “expert” for any purpose, including without limitation for the
purposes of Section 11 of the Securities Act of 1933, as a result of being designated or
identified as an audit committee financial expert. The designation or identification as an
audit committee financial expert does not impose on such person any duties, obligations, or
liabilities greater than the duties, obligations, and liabilities imposed on such person as a
member of the audit committee and board of directors in the absence of such designation or
identification.

1 The nature of the services include assurance and related services reasonably related to the performance of the audit of
financial statements not included in Audit Fees.
2 The nature of the services include tax compliance, tax advice and tax planning.
3 The nature of the services include a review of compliance procedures and attestation thereto.

(e)(1) Audit Committee Pre-Approval Policies and Procedures:
The registrant’s audit committee (the “Committee”) has adopted policies and
procedures with regard to the pre-approval of services. Audit, audit-related and tax
compliance services provided to the registrant on an annual basis require specific pre-
approval by the Committee. The Committee also must approve other non-audit services
provided to the registrant and those non-audit services provided to the registrant’s affiliated
service providers that relate directly to the operations and the financial reporting of the
registrant. Certain of these non-audit services that the Committee believes are a) consistent
with the SEC’s auditor independence rules and b) routine and recurring services that will
not impair the independence of the independent accountants may be approved by the
Committee without consideration on a specific case-by-case basis (“general pre-approval”).
The term of any general pre-approval is 12 months from the date of the pre-approval, unless
the Committee provides for a different period. Tax or other non-audit services provided to
the registrant which have a direct impact on the operation or financial reporting of the
registrant will only be deemed pre-approved provided that any individual project does not
exceed $10,000 attributable to the registrant or $50,000 for all of the registrants the


Committee oversees. For this purpose, multiple projects will be aggregated to determine if
they exceed the previously mentioned cost levels.
Any proposed services exceeding the pre-approved cost levels will require specific
pre-approval by the Committee, as will any other services not subject to general pre-
approval (e.g., unanticipated but permissible services). The Committee is informed of each
service approved subject to general pre-approval at the next regularly scheduled in-person
board meeting. At this meeting, an analysis of such services is presented to the Committee
for ratification. The Committee may delegate to one or more of its members the authority to
approve the provision of and fees for any specific engagement of permitted non-audit
services, including services exceeding pre-approved cost levels.

(e)(2) None of the services described in each of Items 4(b) through (d) were approved by
the audit committee pursuant to paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X.

(f) Not Applicable

(g) Affiliates’ Aggregate Non-Audit Fees:

  Current Fiscal Year  Previous Fiscal Year 
               Entity Name  End  End 
 
WCMA Tax-Exempt Fund  $414,333  $411,849 
Master Tax-Exempt LLC  $414,300  $411,800 

(h) The registrant’s audit committee has considered and determined that the provision of
non-audit services that were rendered to the registrant’s investment adviser (not including
any non-affiliated sub-adviser whose role is primarily portfolio management and is
subcontracted with or overseen by the registrant’s investment adviser), and any entity
controlling, controlled by, or under common control with the investment adviser that
provides ongoing services to the registrant that were not pre-approved pursuant to paragraph
(c)(7)(ii) of Rule 2-01 of Regulation S-X is compatible with maintaining the principal
accountant’s independence.

Regulation S-X Rule 2-01(c)(7)(ii) – $407,500, 0%

Item 5 – Audit Committee of Listed Registrants – Not Applicable

Item 6 – Investments

Item 10 – Submission of Matters to a Vote of Security Holders – The registrant’s Nominating and
Governance Committee will consider nominees to the board of directors recommended by


shareholders when a vacancy becomes available. Shareholders who wish to recommend a
nominee should send nominations which include biographical information and set forth the
qualifications of the proposed nominee to the registrant’s Secretary. There have been no
material changes to these procedures.

Item 11 – Controls and Procedures

11(a) – The registrant’s principal executive and principal financial officers or persons performing
similar functions have concluded that the registrant’s disclosure controls and procedures (as
defined in Rule 30a-3(c) under the Investment Company Act of 1940, as amended (the
“1940 Act”)) are effective as of a date within 90 days of the filing of this report based on the
evaluation of these controls and procedures required by Rule 30a-3(b) under the 1940 Act
and Rule 15(d)-15(b) under the Securities Exchange Act of 1934, as amended.

11(b) – There were no changes in the registrant’s internal control over financial reporting (as
defined in Rule 30a-3(d) under the 1940 Act) that occurred during the second fiscal quarter
of the period covered by this report that have materially affected, or are reasonably likely to
